Me too. I've squirreled 2 barrelsaway, but each is sketchy. One has terrible bayo band wear. The other is import marked and has band wear.
There are a lot of IP receivers. The 3500 submitted weren't accepted, but there were a lot more receivers and other parts made. I've read that maybe 50k? If you break down the parts at retail-ish prices based on per part prices, you come very close to the $1700.
Rec is 1200-ish,
just a common trigger group is 125. But didn't that one have a push safety? More money.
Slide 75
bolt 90-120
even an import barrel can bring 50-75.
Sights are 50 for the pair
stock and metal is at least 50
